No antibodies associated with ganglioside or autoimmune encephalitis (against NMDA-R, CASPR2-R, AMPA1-R, AMPA2-R, LGI1, GABAB-R, DPPX) or paraneoplastic neurologic syndromes (against CV2/CRMP5, PNMA2, Ri, Yo, Hu, Amphiphysin) were detected in CSF and serum. This evidence concerns the gene DPYSL5 and autoimmune encephalitis.
